Number of electron pairs = \frac{1}{2}[V+N-C+A]
2
1
[V+N−C+A]
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
SbCl_5SbCl
5
:
In the given molecule, antimony is the central atom and there are five chlorine as monovalent atoms.
The number of electron pairs are 5 that means the hybridization will be sp^3dsp
3
B and geometry of the molecule will be trigonal bipyramidal.
Answer:
Eon-an indefinite and very long period of time, often a period exaggerated for humorous or rhetorical effect.
Era
Paleozoic-its end was marked by mass extinctions
mesozoic-between cenozoic and paleozoic
cenozoic- most recent era
period-a length of time
epoch-age
mass extinction- a huge die off of animals
landbridge- a strip of land connecting two large land masses
geographic isolation-island
Explanation:
The thermodynamics of leaching of ilmenite in hydrochloric acid for titania pigment production is an industrial production of nano-sized titanium dioxide (TiO2).
<h3>What is thermodynamics?</h3>
Thermodynamics is defined as the change in the energy of system that brings about work in that system.
The leaching of ilmenite which is a titanium-iron oxide mineral with HCl can lead to the production of titanium dioxide (TiO2).
The use of thermodynamics in this process controls the heat and energy of the leaching system leading to a better yield of final products.

When warm air rises and cool air sinks towards earth surface. what is this known as <u>convection currents.</u>
Explanation:
Convection currents not only occurs in the air but also in other fluids like water. In the air, they are responsible for the blowing of winds of the atmosphere . In the oceans, they are responsible for ocean currents. Convection currents also occur in the mantle and are responsible for tectonic plate movements.
